Authentication and key distribution (AKD) protocols become more and more important in the design of wireless networks. The design criteria of the AKD protocols include the scalability, the communication efficiency, the computational efficiency and the robustness of security. In this paper, we first analyze the vulnerabilities of an AKD protocol for wireless networks under three types of attacks. Then,...
Fast re-authentication schemes for mobile stations are essential during handover between access points in wireless local area networks. Although lots of research resources have been put into the reduction of re-authentication latency, these schemes developed so far seem to either suffer from heavy overhead or have weak security. This paper proposes a novel ticket-based approach to deal with the problem...
Available WLAN Mesh network access protocols and trusted network connect protocols can not satisfy the performance and security requirements of WLAN Mesh networks in trusted environment. A provably secure trusted access protocol MN-TAP for the WLAN Mesh Networks is proposed. Such protocol will achieve authentication and key confirmation among the access requestor, policy enforcement point and policy...
In this paper, a collusion-resistant matrix system (CRMS) for group key managements is presented. The CRMS is defined as a collection of subsets of users, and the keys held by users in CRMS are organized in a hierarchical matrix manner. After describing the join and leave protocols, we prove that CRMS has lceil2N/trceil-collusion resistant capability. Moreover, the suggestion of how to select the...
